GAN-BODY-MAKIN G MACHINE. I

Specification of Letters Patent.

To all whom it may concern: I

Be it known that I, LEE O. SHARP, a citizen of the United States, residing in Plattsmouth, in the county-of Cass and State of Nebraska, have invented a new and useful Improvement in Oan-Body-Making Machines, of which the following is a specification. 9

My invention relates to improvements in can body making machines, and more particularly to improvements in look seam can the same essentially soldering device, preferablya series by which the solder body machines.

The object of my invention is to provide a lock seam can body machine ofa simple,

efficient and durable construction, by means of which rectangular canbody blanks may be rapidly and cheaply formed into lock .seam can bodies and the seams thereof efficiently and perfectly solderedwith a minimum amount of solder. 7

My invention consists in the means I employ to practically accomplish this result, comprising a horn around which the rectan ular can body blank is folded or formed, folfing wings for wrapping the blank around the horn, a bumper for com ressing the interlocked hooks or edge folds of the blank into a folded or look seam, a feeder for slippin or moving the can body along the horn, a ribbon solder spool, a ribbon solder feeder for feeding the ribbon solder forward at intervals, the same being coated on one side with .a sticky or adherent flux so that the strip'of the ribbon solder will adhere to the seam portion of the can body blank when pressed thereon, a ribbon solder cutter for cutting a narrow strip of solder from the ribbon and pressing it upon or against the seam portion of the can body and a fusifng or 0 gas jets arranged above the horn, and under which the can body thin sheet solder stuck thereon is passed, and is fused and flowed into the seam.

My invention also consists in the novel construction of parts and devices, and in the novel combinations of parts and devices herein shown and described.

In the accomp nying' drawing formin a part of this s cc fication, Figure l is a p an View of a 100 seam can body making machine embodying my invention, the same with the flux strip ofshowing lonly those parts of the can body formin mechanism to which my invention 's applied and with which my devices cooperate. Fi 2 is a side elevation. 3 is a vertica section on line 3-3 of big. 1,. Fig. 4 is a detail vertical section on line 4+4 of Fig. 1 Fig. 5 is a detail Vertical section on line 5.5 of Fig. 1; Fig.- 6 is a detail elevation of the horn showin the folding wings and bumper of the b0 y forming mechanlsm. Fig. 7 is a .detail perspective view of'a ortion of the solder strip.

In said rawing, A represents the frame of the machine, B is the horn around which the can body blank X is wrap ed by the folding wings O, and E the bumper by which the seammg flanges or meeting edges as of the blank X are pressed together into a lock seam m and the can body feeder by which the can body blanks are slipped along the horn successively from the station where the meeting edges or hooks a: of the blank are formedto the station, where the blank is Wrapped around the horn and the seam bumped, and to the station where the blanks receive the fluxed solder stri y as it is cut from the solder ribbon or sl eet Y and finally past the fusing or soldering device. This feeder D referably. consists of a reciprocating slide urnished with a series of sprm held hooks or pawls d, adapted to engage t e can body blanks and. move them along as re Hired. F is a spool or reel upon which t e solder ribbon Y 1s wound, the same being'in width equal to the length of the can body and from which it is intermittently fed bythe solder ribbon feed device G to the solder strip cutter H. The solder ribbon or sheet Y 1s coated on one side with a sticky or adherent flux yby which the solder strip cut from the ribbon is caused to firmly adhere to the seam portion of the can body blank :0.

The solder ribbon feed device preferably consists of a pair of feed rolls G G, one above and one below the solder ribbon Y. One of these feed rolls G, preferably the upper one or its shaft g is provided with a ratchet g and is intermittently rotated by a pawl 9 upon the pawl arm or lever g through the connecting link 9 and rock shaft 9 having an arm g connected 'to said link, and an arm 9 engaged and operated by a cam g on the slide D and which is connected to and "Patented June 213, 1908..

timed with moving devices of the lock seam can body forming mechanism. A guide K having upright wings K? for the solder ribbon extends from the spool F to the feed rolls body b G G and from the feed rolls G G to: the horn B and to the solder cutter H H The lower or stationary solder cutter H is arranged directly over the horn and'slightly to one side of the seam or portion of the can body blank upon which the narrow solder strip y, cut from the solder ribbon Y is to be pressed by the upper or reciprocating cutter H. The cutter H preferably has a substantially flat or square lower face h,so that the same device will operate to cut the narrow solder strip (1 from the solder ribbon Y, and also to press such narrow solder strip y, firmly upon the seam of the can body blank and cause the same to properly adhere thereto by the sticky flux on the under side of the solder strip. The movable or reciprocating solder cutter H is preferably intermittently fused and the solder flowed into the seam,

consists preferably of a gas pipe arranged directly above the horn B, and provided with a series of burner orifices or jets m arranged in line with the horn B and with the seam of the can body to be soldered. I claim:
